You can move, rotate, or resize items on your Freeform board. You can align, distribute, or group them, and move them to the background or foreground. You can turn on a grid or guides to help you position items, and lock items when you want to prevent any further changes.
Go to the Freeform app , then tap Back or Front.
Resize it: Drag a blue dot.
In text boxes, drag a green dot to resize both the box and the text within it.
Match its size to another item: Start resizing, then use a second finger to touch and hold the item whose size you want to match. When the words Match Size appear, lift both your fingers at the same time.
